A SWITCH IN A PROTECTIVE INTERLOCKING CIRCUIT SHOULD BE 
USED WITH AT LEAST ONE OTHER DEVICE THAT WILL PROVIDE A 
REDUNDANT PROTECTIVE FUNCTION, AND THE CIRCUIT SHOULD 
BE SO ARRANGED THAT EITHER DEVICE WILL INTERRUPT THE 
INTENDED OPERATION OF THE CONTROLLED EQUIPMENT.  
(PROPOSED NEMA ICS 2-225.95 St'd.)

SERVICING ENERGIZED INDUSTRIAL CONTROL EQUIPMENT CAN 
BE HAZARDOUS.  SEVERE INJURY OR DEATH CAN RESULT FROM 
ELECTRICAL SHOCK, BURN OR UNINTENDED ACTUATION OF 
CONTROLLED EQUIPMENT.

RECOMMENDED PRACTICE IS TO DISCONNECT AND LOCK OUT 
CONTROL EQUIPMENT FROM POWER SOURCES, AND 
DISCHARGE STORED ENERGY IN CAPACITORS, IF PRESENT.  IF IT 
IS NECESSARY TO WORK IN THE VICINITY OF ENERGIZED 
EQUIPMENT, ONLY QUALIFIED PERSONNEL SHOULD BE 
PERMITTED TO PERFORM SUCH WORK , USING ALL APPLICABLE 
SAFETY PRACTICES AND PROTECTIVE EQUIPMENT.

• Unless specifically designed for such service limit switches 

SHOULD NOT BE submerged in or splashed with oils, 
coolant or other liquids. CONSULT FACTORY. 

• Limit switches MUST NOT BE used in locations where 

temperature or atmospheric conditions are beyond those for 
which they have been specifically designed.

• Power from different sources MUST NOT BE connected to 

the contacts of one limit switch unless specifically designed 
for such service.

• Limit switches MUST BE used within their contact ratings 

and the appropriate limits switch bulletin for acceptable 
environmental conditions in which the switch has been 
designed to function properly.

• Limit switches SHOULD BE mounted rigidly and in readily 

accessible locations, with suitable clearances to permit 
easy service and replacement when necessary. Cover 
plates SHOULD face the maintenance access point.

• Limit switches SHOULD BE placed in locations where 

machining chips do not accumulate under normal operating 
conditions to avoid chip interference with the lever 
operation.

• Opposite polarities MUST NOT BE connected to the 

contacts of one limit switch unless the limit switch is 
specifically designed for such service.

Instructions for proper applications and uses of 

COMPACT LIMIT SWITCHES

EXPERIENCE HAS SHOWN THAT THE MECHANICAL 

AND ELECTRICAL OPERATING LIFE OF A LIMIT 

SWITCH IS INFLUENCED TO A LARGE DEGREE BY 

PROPER INSTALLATION AND APPLICATION 

PROCEDURES.  THIS PUBLICATION IS INTENDED TO 

BE USED AS A GUIDE.

LOW AND HIGH TEMPERATURE LIMIT SWITCHES ARE 
MANUFACTURED USING SPECIAL MATERIALS AND 
COMPONENTS NOT AVAILABLE AS MAINTENANCE KITS 
FROM THE FACTORY. DISCARD DAMAGED OR WORN 
LIMIT SWITCHES AND REPLACE WITH NEW SWITCHES 
FROM THE FACTORY.

* Rotating it clockwise 90° makes it a clockwise-only switch. Rotating it counter-clockwise makes it a counter-clockwise-only switch. 

(Switch operates both directions when shipped).
